Be it known that I, JOSEPET. MARTIN, of the city, countyf'and State of New York, have-invented a new and improved MarineGrapple'; and I do hereby declare that the following is a full, clear, and exact description thereof, which willenable othersskilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ofv this specification, in which- Figure 1 Arepresents a side view of my improvedA marine grapple.

Figure 2 is an end viewof the same. l

Similar letters of reference indicate corresponding parts.

This invention relates to a new marine grapple, which is a simpliiied and improved moeliticationof that for which Letters Patent were granted me on the eleventh day of July, v 1854.

The present invention consists in arranging the claws .or hooks on a single bar or beam, which is perforated or slotted, so that the claws can be adjusted on `it to adapt them to vessels ot' suitable breadth. By thus doing away with the extension-beam, that -was used in the aforesaidpatented device, the apparatus is not only malle considerably cheaper, but also` muchstronger. v v

A, in the drawing,represents a beam of iron, -wood, or other suitable material, made of suitable .length and cross-section. l v I lB B are the claws. v 'They are formed on the lower ends ofbars C'C,`that `arepivotedA to the beam by means ot' suitable pivots, a a, as shown; f

The beam A has a series of holes, b b, or a slot, orisotherwise so arranged 'that the pivots a a can be brought together or further apart, as may be desired. The bars C C are in a similar-"manner, by means of holes, c c, slots, or other devices, so arranged that they can be adjusted up and down on the beam, for the purpose of bringing the hooks B to a higher or'lower portion of Vvthe vessel, as may be desired.

The device is thus applicable to broad or narrow,l to deep or flat vessels, and is operated by means ofcbains or ropes, D D, which are fastened to the upper ends of the lever-C.A

From ropes or 4chains, E, which are fastened to the ends of the bea-m A, the" whole device is suspended.

The operation ofthe apparatus will be clearly understood by reference to iig..1. Each lever C may carry any desired number of claws B, or may have one single claw at its-lower end. Having thus described my invention, -I claim as new, and desire to secure byLetters Patent- A marine grapple, consisting ofa solid beam, A, to which the levers C, carrying the grappling-jaws B, are pivoted, when said bars are adjustable towards 'or away from each other, on the beam A, and also upfandldown adjustable on the same, substantially as and for the purpose herein shownand described.
